Crops cultivated in the farm crop field in the present invention are not limited as long as they belong to cultivate which are generally cultivated as crops.

These plant cultivate include plants, to which resistance to herbicides has been imparted by a classical breeding method or genetic recombination technology, the herbicides being protoporphyrinogen oxidase inhibitors such as flumioxazin; 4-hydtoxyphenylpyruvate dioxygenase inhibitors such as isoxaflutole; acetolactate synthase inhibitors such as imazethapyr and thifensulfuron-methyl; acetyl coA carboxylase inhibitors such as sethoxydim; 5-enolpyruvylshikimate-3-phosphate synthase inhibitors such as glyphosate; glutamine synthetase inhibitors such as glufosinate; auxin type herbicides such as 2, 4-D and dicamba; and bromoxynil.

Examples of the crop, to which resistance to herbicides has been imparted by a classical breeding method, include corn which is resistant to an imidasolinone type acetolactate synthase inhibiting herbicide such as imasethapyr, and which has already been sold under the trade name of Clearfield (registered trademark). Such a crop also includes STS soybean which is resistant to a sulfonylurea type acetolactate synthase inhibiting herbicide such as thifensulfuron-methyl. Similarly, examples of the plant, to which resistance to an acetyl CoA carboxylase inhibitor such as a trione oxime or aryloxyphenoxypropionic acid type herbicide has been imparted by a classical breeding method, include SR corn.

Examples of the plant, to which resistance to herbicides has been imparted by genetic recombination technology, include corn, soybean and cotton, each having resistance to glyphosate, and which have already been sold under the trade names of RoundupReady (registered trademark), Agrisure (registered trademark) GT, and Gly-Tol (registered trademark). Similarly, plants, to which resistance to herbicides has been imparted by genetic recombination technology, include corn, soybean and cotton, each having resistance to glufosinate, and they have already been sold under the trade name of LibertyLink (registered trademark) . There are corn and soybean cultivars , which are resistant to both glyphosate and ALS inhibitors, and are sold under the trade name of Optimum (registered trademark) GAT (registered trademark). Similarly, there is soybean, to which resistance to an imidazolinone type aceto lactate synthase inhibitor has been imparted by genetic recombination technology, and which has been developed under the trade name of Cultivance. Similarly, there is cotton, to which resistance to bromoxynil has been imparted by genetic recombination technology, and which has already been sold under the trade name of BXN (registered trademark). There is soybean, which is resistant to both glyphosate and dicamba, and has been developed under the brand of RoundupReady (registered trademark) 2 Xtend. Similarly there is cotton, which resistant to both glyphosate and dicamba.

Crops having resistance to both phenoxy acid type herbicides such as 2,4-D, MCPA, dichlorprop and mecoprop, and aryloxyphenoxypropionic acid type herbicides such as quisalofop, haloxyfop, fluasifop, didofop, fenoxaprop, metamifop, cyhalofop and clodinafop can be fabricated by introducing a gene encoding an aryloxyalkanoate dioxygenase (Wright et al. 2010: Proceedings of National Academy of Science. 107 (47): 20240-20245). Cultivars of soybean and cotton, which show the resistance to 2,4-D, have been developed under the brand of Enlist.

By introducing a gene encoding a 4-hydroxyphenylpyruvate dioxygenase (hereinafter referred to as HPPD) inhibitor which exhibits resistance to HPPD inhibitor, and thus plants having resistance to the HPPD inhibitor can be fabricated (US 2004/0058427). By introducing a gene capable of synthesizing homogentisic acid as a product of HPPD through another metabolic pathway, homogentisic acid is produced even in the presence of a HPPD inhibitor, and thus making it possible to fabricate plants which exhibits resistance to the HPPD inhibitor (WO 02/036787). By introducing a gene capable of excessively expressing HPPD, HPPD is produced in the amount which does not exert an adverse influence on the growth, of the plant even in the presence of a HPPD inhibitor, and thus making it possible to fabricate plants which exhibit resistance to the HPPD inhibitor (WO 96/38567). By introducing aforementioned gene capable of excessively expressing HPPD and also introducing a gene encoding a prephenate dehydrogenase so as to increase the production amount, of p-hydroxyphenylpyruvic acid as a substrate of HPPD, and thus making it possible to fabricate plants which exhibit resistance to the HPPD inhibitor (Rippert P et al. 2004 Engineering plant shikimate pathway for production of tocotrienol and improving herbicide resistance. Plant Physiol. 134; 92-100).

The hybrid toxins are fabricated by a novel combination of the different domains of these proteins, using genetic recombination technology. The known partially deficient toxin is Cry1Ab, in which a part of amino acid sequence is deficient. In modified toxins, one or more amino acids of a natural toxin are replaced. Examples of these toxins and transgenic plants capable of synthesizing these toxins are described in EP-A-Q 374 753, WO 93/07278, WO 95/34656, EP-A-Q 427 529, EF-A-451 978 , and WO 03/052073 .
